I would start with a very practical test. Take the cover off and
transmit high power through the existing balun for a while. Stop
transmitting and feel the balun to see if it is hot. If it is not, you
don't have a problem. If it is hot, then think about solving it.
Ten Tec has always had pretty good engineers. I find limited value in
trying to improve on their work. The only thing I've had to do with my
229s and 238s is to replace a few of the fixed caps that can overheat
with high power operation (1.5kW) and certain extremes of antenna
impedance.
